Abstract

A power supply module (62) includes an input (VIN) and an output (VOUT) and a power converter for supplying power from the input to the output. A controller (27) controls the amount of power supplied from the input to the output in response to a feedback circuit (35) and a module current sensing circuit (49) senses module output current at the output. A microprocessor (51) selectively adjusts voltage in the feedback circuit in response to the module output current sensed by the module current sensing circuit (49).
